GS3 w/ case

Hi Scuba, sorry for the template response we have been pretty busy over here.

Glad that Lokkie has been able to come on and answer a lot of questions (probably better than me).

However the case issue is something that has been bugging us. I was playing with my Nexus 5 with a case today and was able to get some reads with it. But it wasn't reliable at all. So the question we have to ask is how can we make the experience better for people that have a case. I don't think we can officially tell people to cut holes in there phone case, so maybe the solution is that we need to see if we can source or manufacture a phone case ourselves, with a pre-cut sweet spot hole. This will take some time though as we need as much phone information as possible.

Ah, that's a pain - I'm always hoping that it's the simple things that are causing the issues.
I've been looking at the powermat and other inductive charging devices, they're not really NFC based but it's similar technology with induction loop antennas so there's the potential that it will interfere with any other induction based device that you use. If your NFC antenna is under where the charger loop is I can see that causing issues, but we wont know until someone tries it and tells us. Your mission should you choose to accept it Agent imscuba...

Tom + imscuba - flomio have this on their website: [url:hvmoyk3a]http://flomio.com/shop/nfc-readers/nfc-band-aid/[/url:hvmoyk3a].
That appears to have the potential to increase readability with difficult devices but I'm not sure if it's truly available or how well it would really work. If it worked the way it appears to it would negate the need for a custom case.

unfortunate with the powermat, its not really gonna cost me much to find out, so i will find out. hopefully it makes things better. i have also seen a couple of cases that supposedly boost nfc, though they are not cheap. i just last night drilled a countersunk hole in the back of a new case and it seems to work fine, though i will be exploring additional options

There is always the chance that it would act to enhance the NFC reader portion of your phone a little, as long as it isn't powered when it's not used for charging. Passive repeaters are generally more gimmicky in real life than they are useful. But it's a possibility, so best of luck brave soul and all that.
At least you can test this without it costing anything eh!
A 'proper' booster case would simply replace the antenna and shift it further towards the outside of the phone while being connected to the points where the original antenna was connected. This and passive repeaters are the only type we're allowed to have on our handheld communications devices.
Active repeaters change too many variables and long term RF exposure outside the limits that we currently have is an unknown.
Anyway, I'm going OT there. The 'NFC Band Aid' that I posted earlier was an example of a passive repeater, with the 'Band Aid' part being close to the phone NFC antenna and the little hockey puck antenna being physically connected to it and acting as a relay of sorts.
It works after a fashion but tends to be very lossy. But being two part like that, it 'works'.
I'm sceptical of booster cases and claims that charging loops can enhance the performance of phone NFC without actually being a part of that device because it's only a single part of a chain. NFC antennas being different sizes in different devices and all, you couldn't really guarantee that it would 'pull' the signal like a director element from the phone or simply act as a reflector.

Ach, it's late and I haven't had enough coffee. I'll try that one again later.

so, i just got the qi wireless charging receiver module for the gs3 (bought the adapter and the company sent me a bunch of other free stuff with it) and unfortunately it does interfere with the ring, the regular tags work fine though

Ah, that's a pain. I did wonder how it would go - thanks for letting us know.
oh, its fantastic, a little irritating that the charging pad beeps when it connects though. some models from various companies it beeps when it finishes charging and disconnects, then when it drops back down to 98-99% it connects again, etc. im hoping my model doesnt, cause ill have a continuous beeping all night.

i will have to do a little more digging to see if there is something similar that would work with NFC even if it means getting rid of the wireless charging. im not too sure if those 2 little connectors the wireless charging adapter are using can be used for NFC or if they are purely for power.

I always figured they were a cool idea but I've never been able to play with one.
Where's the location of the additional antenna for the charging? If it wasn't right over the top of the GS3 battery it wouldn't interfere so much. I don't s'pose there's any way to shift it?

I always figured they were a cool idea but I've never been able to play with one.

the little sticker receiver thing they have actually adheres to the battery, i think i would likely need to take it apart and modify it to get it to not surround the battery. im hopeful that there might be something out there that is basically this same adapter but handles nfc instead of wireless charging. its a shame that the nfc band aid is so expensive

The only way we'd be able to use the NFC band aid to do this would be to put it on top of the battery, then the power adapter and have a hole in the case for the extension antenna from the NFC band aid - it's basically a passive repeater, so there's still the chance that there'd be interference because of stacking so many antenna elements.

I suspect it would do some very strange things.

I wonder if it's possible to get a GS3 type antenna (for the connector) that is not an integral part of the battery, that way you'd possibly be able to shift it away from there.

Ah, right - yeah the Band aid is a passive repeater. There'd be absolutely nothing stopping someone from using a battery that didn't have the NFC antenna though, and just connecting another antenna to the same points that a standard one does.
It wouldn't be perfect, but it'd work as long as everything matched up properly.

hey lokki, i figured since you are a forum admin you might be involved with the whole project and might be able to answer my question rather than email the support email. i just saw the update that mentions faulty rings. how are we supposed to know if our ring is faulty? when i get my ring to work it seems like the read area is less than the size of the sweet spot sticker, so im not sure if thats as intended and the gs3 just doesnt like it or if it might be the ring. if you aren't involved in the whole project and just simply manage the forums i can send an email in or create a thread in the appropriate place.

Hi mate, I'm just a fan and persisted my way into a moderator position. Tom, John and Chris are the droids you're looking for if you need to throw praise, money or lukewarm custard. Tom's answer is the one to pay heed to though, the GS3 and GS4 seem to have rather small sweet spots that are really picky at times (and mileage between phones really varies a lot) but if they work at all then the ring is fine. :-)
